Of course, many Linux users are Windows expatriates, or still use Windows in some capacity, so they are already accustomed to seeing malware sent via email.

I would say one thing on the average Linux user's side is the number of hoops this kind of malware would have to jump through to be installed. First they have to untar the package, possibly build it or run a script, and unless they are foolish enough to run the script as root, they still only will see damage within /home.

This proves that proper security procedures (such as "Don't run random programs that are emailed to you as root") have their place in any OS.
